Abstract

L'invention se rapporte à un dispositif pour faire passer un fil à travers un tube au moyen d'une unité à écoulement spiral par effet Coanda. Ce dispositif est pourvu d'une unité d'avance du fil à écoulement par effet Coanda, qui sert à acheminer un fil conducteur ou un fil de guidage, cette unité d'avance étant disposée au niveau d'une ouverture d'aspiration-introduction du dispositif pour faire passer le fil, de façon à permettre l'introduction du fil selon le mode énoncé ci-dessus. Un dispositif d'alimentation est en outre placé à l'extérieur de l'unité d'avance à écoulement par effet Coanda. Il est ainsi possible d'obtenir une introduction stable du fil à des vitesses élevées et avec un niveau d'efficacité élevé. Grâce à cette invention, il est également possible de faire passer un mince fil de fibre optique à travers un tube sur une longue distance.
